10 Pack Sterile Thick Plastic Petri Dishes with Lid, 90mm Dia x 15mm Deep Clear 3 Vents Petri Dish for Lab Science Experiment

Good Petri dishes. 10 dish were in a sterile sealed bag. I only poured 9 because I never made enough agar but I got no contamination while pouring inside a SAB. Would love to be able to order in bulk.

I really do wish they would stop using camera angles to enhance their product.

This review goes along with the one for the logbook. My nephew had a school science experiment, of his choice, to complete in 30 days. He decided he would test surfaces and see just how dirty they were. Well, wasn't he surprised to see all that stuff growing from the agar I poured in the dishes? Stuff he swabbed from the counter, light switches, floor (in varying places), doorknobs, and even the toilet seat! They hold up nicely, as he is a little clumsy and dropped a couple, none broke. It might have affected the outcome of the experiment, though. But it was only 2, I believe. The value is great, getting 10 in one go. I was concerned when I bought them about the lid-locking, and most did. The ones that didn't, we taped shut. The experiment was a partial success as it didn't get him to wash his hands more often, but the teacher was impressed.

Did the job!

I bought these for my sons science project. These worked fine for his use, but note that they are not sterile which was not an issue for his project. We had no broken one. Also note the two halves are a very loose fit so would not be suitable for experiments requiring a closed space.
